Cave Akari

(Eingestellt am 4. Dezember 2020, 10:00 Uhr von Mark Sweep)

This is a 15x15 Cave/Akari hybrid I created. If it feels a bit overwhelming, make sure to try the 10x10 teaser first.

Cells have to be shaded to create cave walls, such that these walls are orthogonally connected to the edges of the grid. The unshaded cells (the cave) need to remain orthogonally connected to each other to be able to traverse the cave. The cave also needs to be fully lit up, so lightbulbs need to be placed throughout the cave. Lightbulbs light up the cave in each orthogonal direction until a wall is reached. Two lightbulbs are not allowed to see each other.

Every clue in the grid is either a Cave (unshaded) or an Akari clue (shaded). Cave clues indicate how many cave cells it sees in orthogonal directions, including itself. Akari clues are part of the wall and indicate how many lightbulbs are orthogonally adjacent to the clue.

An example of what a finished grid could look like is shown below. Orange cells are lightbulbs.

Solve on Penpa

Lösungscode: For each row: total of lightbulbs + different wall segments, from top to bottom. The example puzzle would be 441224 (e.g. row 1 has 2 lightbulbs and 2 wall segments, so it is a 4 in the solution code). Note: different wall segments mean those that are not connected within that row. So, a wall-cave-wall within a row counts as 2 different wall segments, regardless of whether they do connect outside of that row.

@juhish: Sorry for the late reply. I am glad Uhu was able to help you quickly. I have now updated the solution code description to hopefully make it more clear for any future solvers. Thank you for solving the puzzle!

@juhish: Your solution is correct. You miscount the wall segments. For example, if you have a U-pentomino, the upper side of the U counts as two different wall segments, not as one because it is actually one (big) wall segment.

That was tricky, but very satisfying to complete :)

--- Makes me happy to hear that :)

Great puzzle! The two rulesets combine really nicely in this hybrid.
